Frontend JavaScript Developer (UI/UX Focus)
A Bit About Us
We are a high-growth construction technology company developing integrated hardware and software systems that automate key processes on infrastructure construction sites. Our products are helping modernise the construction industry through digitalisation, automation and intelligent data collection.
Our technology improves road construction quality, extends asset life, enhances health and safety, and helps reduce costs in an industry where efficiency matters.
Why We're Hiring
As we continue to grow across the UK, Ireland and the USA, we are expanding our R&D team to develop the next generation of integrated software and hardware solutions.
We're looking for an experienced Frontend JavaScript Developer with a passion for creating intuitive, polished user experiences. While strong technical skills are essential, we're particularly interested in someone who enjoys designing clean, modern interfaces and understands how thoughtful UI and UX can make complex software simple to use.
You'll work within a small, collaborative team building web and mobile applications, combining frontend development with product design input. The role offers a mix of office and remote working.
